What is the legal blood alcohol concentration limit for drivers under 21 in Puerto Rico?

In Puerto Rico, the legal blood alcohol concentration (BAC) limit for drivers under 21 is 0.00%. This means that any detectable level of alcohol in the bloodstream is considered illegal for novice drivers, reflecting a strict zero-tolerance policy aimed at reducing accidents and promoting responsible driving among young individuals. This law is established to discourage underage drinking and driving, and it serves the broader goal of enhancing road safety for all users. The rationale behind such a policy is that young drivers may be less experienced and more prone to risky behavior when combined with alcohol consumption, thus leading to higher risks of accidents.
